• 中文摘要： 本文以水動力模型來預估以壓縮空氣垂直輸送管中兩相流動時, 在各種不同實驗條件時之空隙度, 壓力, 氣體速度及粒子速度, 孔隙度及壓力實驗結果與理論值極為吻合。
• 英文摘要： Hydrodynamic equations with two continuity equations and two momentum equations in both gas and solid phases were used for the computations of the porosity, pressure, gas velocity and solid velocity simultaneously in the gas-solid transport along a vertical tube with 7.62cm ID. Two different friction coefficients between gas and solid were used in this calculation separately. The predictions of porosity and pressure of the system with various flow conditions were compared with available experimental data, showing that the overall agreement is good.
